Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

2012-10-04T06:29:23+00:00

Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

drm/savage: re-add busmaster enable, regression fix

2012-10-03T00:34:55+00:00

466e69b8b03b8c1987367912782bc12988ad8794 dropped busmaster enable from the
global drm code and moved it to the individual drivers, but missed the savage
driver. So, this re-adds busmaster enable to the savage driver, fixing the
regression.

drm: use drm_compat_ioctl for 32-bit apps

2012-09-05T20:55:02+00:00

Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.

This patch  uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.

This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

drm/savage: clean up reclaim_buffers

2012-07-20T02:50:16+00:00

The reclaim_buffers function of the savage driver actually wants to run
with the hw_lock held - at least there are printks in the call-chain
to that effect. But the drm core only calls reclaim_buffers as used
by savage _after_ forcefully dropping the hwlock (in case it's still
hold by the closing fd).

So do the same idlelock dance as for the other dma drivers and hope
that papers over any issues.

v2: Don't let the idlelock linger around.

drm: checking the wrong variable in savage_do_init_bci()

"dev->agp_buffer_map" is a valid pointer.

drm/savage: fix integer overflows in savage_bci_cmdbuf()

2012-04-10T09:22:51+00:00

Since cmdbuf->size and cmdbuf->nbox are from userspace, a large value
would overflow the allocation size, leading to out-of-bounds access.

drivers/gpu/drm/savage/savage_state.c: add missing kfree

2012-03-20T08:45:31+00:00

Most of the error handling code in this function frees the buffers
kcmd_addr, kvb_addr, and kbox_addr allocated at the beginning of this
function.  These two branches are changed to do the same.

drm: Make the per-driver file_operations struct const

2011-11-11T11:14:47+00:00

From fdf1fdebaa00f81de18c227f32f8074c8b352d50 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven 
Date: Sun, 30 Oct 2011 19:06:07 -0700
Subject: [PATCH] drm: Make the per-driver file_operations struct const

The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.

This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

gpu: add module.h to drivers/gpu files as required.

So that we don't get build failures once the implicit module.h
presence is removed.
